De-laminator apparatus and method

Abstract

A laminating system for bonding, to receiver stock, a lamination sheet of the type including a carrier and a material to be applied to the receiver stock, and for de-laminating the carrier from the receiver stock after the material has been applied to the receiver stock includes a superposed sandwich of the lamination sheet and the receiver stock. A de-lamination leader is associated with one edge of the lamination sheet and the receiver, whereby the carrier can be easily peeled from the receiver stock starting at the one edge. The leader may be between the one edge of the lamination sheet and the receiver stock so that the edge does not laminate to the receiver stock upon application of heat and pressure. Alternatively, the leader may be butt joined to the one edge of the lamination sheet, such as by tape. A pair of adhesive stripes, one stripe being more adhesive than the other, may also be used to join the materials.

What is claimed is: 
     
       1. (Amended) In a laminating system for bonding to receiver stock, a lamination sheet of the type including a carrier and a material to be applied to the receiver stock, and for delaminating the carrier from the receiver stock after the material has been applied to the receiver stock, the improvement comprising; a superposed sandwich of the lamination sheet and the receiver stock: and   a de-lamination leader associated with one edge of the lamination sheet and the receiver wherein the leader has a pair of adhesive stripes, one stripe being more adhesive than the other, whereby the carrier can be easily peeled from the receiver stock starting at the one edge.   
     
     
       2. The improvement as set forth in claim 1 wherein the one stripe is attached to the lamination sheet and the other stripe is attached to the receiver stock. 
     
     
       3. A lamination process for bonding, to receiver stock, a lamination sheet of the type including a carrier and a material to be applied to the receiver stock, and for de-laminating the carrier from the receiver stock after the material has been applied to the receiver stock, the improvement comprising: forming a superposed sandwich of the lamination sheet and the receiver stock with the material between the carrier and the receiver stock:   associating a delamination leader with one edge of the lamination sheet wherein the leader is associated with the lamination sheet by a pair of adhesive stripes, one stripe being more adhesive than the other;   applying heat and pressure to the sandwich and associated leader to thereby laminate the lamination sheet to the receiver stock; and   peeling the carrier from the receiver stock starting at the un-laminated edge.   
     
     
       4. The lamination process as defined in claim 3 wherein the one stripe is attached to the lamination sheet and the other stripe is attached to the receiver stock. 
     
     
       5. In a laminating system for bonding, to receiver stock, a lamination sheet of the type including a carrier and a material to be applied to the receiver stock, and for de-laminating the carrier from the receiver stock after the material has been applied to the receiver stock, the improvement comprising: a superposed sandwich of the lamination sheet and the receiver stock; and   a de-lamination leader between one edge of the lamination sheet and the receiver stock so that said edge does not laminate to the receiver stock upon application of heat and pressure, wherein the leader has a pair of adhesive stripes, one stripe being more adhesive than the other, whereby the carrier can be easily peeled from the receiver stock starting at the one edge.   
     
     
       6. The improvement as set forth in claim 5 wherein the one stripe is attached to the lamination sheet and the other stripe is attached to the receiver stock.
